The testimony on which faith rests is human or Divine. It is human in so far as it is based on human experience and observation. It is Divine in so far as it rests upon the direct revelation of God. Faith in man is continually exercised in business and in all the departments of life. It is necessary to the very existence of society. Faith in God moves in another sphere. Its objects are not seen or temporal, and they do not rest for proof upon the testimony of man. It receives and assents to statements which are made on the authority of God, who knows all things, who therefore cannot be deceived, and who is truth and therefore cannot deceive us. On this Divine rock of faith, and not upon her own knowledge, the Christian Church rests. "If we receive the witness of men, the witness of God is greater."[013] Among Christian virtues faith stands first. It must precede everything else. It is the foundation on which all Christian character and life are built. "He that cometh unto God must believe that he is."[014] "Without faith it is impossible to please God."[015] That which Christian faith realises and grasps is expressed in doctrine. Faith is not a separate and self-dependent grace. Its existence and growth arise from those things which are believed, and therefore it is necessary to study and understand, as far as we can, the doctrines of the Christian faith before we can possess or manifest belief. It is important that we should have a definite knowledge of these doctrines; that we should study them in relation to the Scriptures upon which they profess to be founded, and that we should be in a position to defend them against assailants. Thus faith will gather strength, and believers will be "ready always to give an answer to every man that asketh them a reason of the hope that is in them with meekness and fear."[016] SECTION 2.--GOD--[017] The existence of God is the basis of all religious belief. If there is no God, there is no moral obligation. If there is no Almighty Being to whom men owe existence, and to whom they must give account, worship is a vain show and systems of religion are meaningless. Theologians, therefore, from the days of the first Christian apologists to our own time, have endeavoured to establish by proof the doctrine of the Divine existence. To those who accept the authority of Scripture the existence of God is a fact which no argument can overthrow; but as there are many who reject this authority, evidence has been sought elsewhere than in Scripture to establish the doctrine. The arguments for the Being of God are mainly threefold, being drawn: (_a_) from the consciousness of mankind; (_b_) from the order and design that are manifest in the universe; and (_c_) from the written revelation which claims to have come to men from God Himself.
